1. 1. Homocysteine in cardiovascular disease with special reference to longitudinal changes

   Författare :Johan Hultdin; Torbjörn Nilsson; Bertil Kågedal; Umeå universitet; []
   Nyckelord :Medical sciences; homocysteine; methylenetetrahydrofolate reductase MTHFR ; first-ever stroke; first-ever myocardial infarction; longitudinal; prospective; risk factor; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

   Sammanfattning : Abnormalities in homocysteine metabolism have been suggested as risk factors for stroke and myocardial infarction. In retrospective studies, elevated levels of total plasma homocysteine (tHcy) and/or methylenetetrahydrofolate reductase (MTHFR) 677C>T polymorphism have indicated an increase in risk. LÄS MER

4. 3. Homocysteine and Coronary Artery Disease With special Reference to Biochemical Effects Of Vitamin Therapy

   Författare :Torfi Jonasson; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; pyridoxine.; oxidative stress; lipid peroxidation; inflammation; homocysteine; endothelial function; folate; F2-isoprostanes; cystatine C; Acut coronary syndrome; cardiovascular disease; asymmetric dimethylarginine; cobalamine;

   Sammanfattning : An elevated plasma level of homocysteine has been suggested as a risk factor for cardiovascular disease. The objectives of this thesis were to study the influence of renal function on homocysteine levels in patients with coronary artery disease and to explore the association of elevated plasma levels of homocysteine to oxidative stress, inflammation, and endothelial dysfunction.

   Sammanfattning : Background: Globally, cardiovascular diseases (CVD), including myocardial infarction (MI) and stroke, are the leading cause of illness and death and constitute a significant part of the disease burden in Sweden and Western Europe. Age, hypertension, smoking, obesity, dyslipoproteinemia, diabetes, and impaired renal function are considered established risk factors for CVD. LÄS MER

7. 5. Genetic variation in the folate receptor-alpha and methylenetetrahydrofolate reductase genes as determinants of plasma homocysteine concentrations

   Författare :Anna Böttiger; Torbjörn Nilsson; Henrik Zetterberg; Örebro universitet; []

   Sammanfattning : Elevated total plasma homocysteine (tHcy) is a risk factor for cardiovascular disease and neurocognitive disease such as dementia. The B vitamins folate and B12 are the main de terminants of tHcy. tHcy concentration can also be affected by mutations in genes coding for receptors, enzymes and transporters important in the metabolism of Hcy.
